This book contains a selection of the papers presented at the XVII SIGEF Congress. It presents fuzzy logic, neural networks and other intelligent techniques applied to economic and business problems. This book is very useful for researchers and graduate students aiming to introduce themselves to the field of quantitative techniques for overcoming uncertain environments. The contributors are experienced scholars of different countries who offer real world applications of these mathematical techniques.

The objective of the book is to discuss and explain the problems caused by the investment process in a world that is so full of change that it has become uncertain. For this reason the author presents a very wide range of theoretical and technical elements gathered from the new mathematics of uncertainty, both in its numerical and non-numerical aspects. In this regard an important role is played by the theories of fuzzy sub-sets, forgotten effects, affinities, expertons and many others that are being introduced with such success, in an attempt to arrive at a solution to the complex ...
